Carbon Dioxide at NOAA’s Mauna Loa Observatory reaches new milestone: Tops 400 ppm

Mona Loa Observatory After Snowstorm
On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958. Independent measurements made by both NOAA and the Scripps Institution of Oceanography have been approaching this level during the past week. It marks an important milestone because Mauna Loa, as the oldest continuous carbon dioxide (CO2) measurement station in the world, is the primary global benchmark site for monitoring the increase of this potent heat-trapping gas.
Carbon dioxide pumped into the atmosphere by fossil fuel burning and other human activities is the most significant greenhouse gas (GHG) contributing to climate change. Its concentration has increased every year since scientists started making measurements on the slopes of the Mauna Loa volcano more than five decades ago. The rate of increase has accelerated since the measurements started, from about 0.7 ppm per year in the late 1950s to 2.1 ppm per year during the last 10 years.
“That increase is not a surprise to scientists,” said NOAA senior scientist Pieter Tans, with the Global Monitoring Division of NOAA’s Earth System Research Laboratoryin Boulder, Colo. “The evidence is conclusive that the strong growth of global CO2 emissions from the burning of coal, oil, and natural gas is driving the acceleration.” Continue reading

The Scripps CO2 measurements at Mauna Loa have been supported for many years by the U.S. Department of Energy (DOE), and have more recently been supplemented by Earth Networks, a technology company that is collaborating with Scripps to expand the global GHG monitoring network.

Osterholm on “contagion exhaustion”
Posted on May 10, 2013 by hanshowe
From Crof’s H5N1 Blog…

Via The New York Times, Dr. Michael Osterholm, director of CIDRAP, writes today’s must-read: The Next Contagion – Closer Than You Think. Excerpt:
There has been a flurry of recent attention over two novel infectious agents: the first, a strain of avian influenza virus (H7N9) in China that is causing severe respiratory disease and other serious health complications in people; the second, a coronavirus, first reported last year in the Middle East, that has brought a crop of new infections.
While the number of human cases from these two pathogens has so far been limited, the death rates for each are notably high.
Alarmingly, we face a third, and far more widespread, ailment that has gotten little attention: call it “contagion exhaustion.” News reports on a seemingly unending string of frightening microbes — bird flu, flesh-eating strep, SARS, AIDS, Ebola, drug-resistant bugs in hospitals, the list goes on — have led some people to ho-hum the latest reports.
Some seem to think that public health officials pull a microbe “crisis du jour” out of their proverbial test tube when financing for infectious disease research and control programs appears to be drying up. They dismiss warnings about the latest bugs as “crying wolf.” This misimpression could be deadly. Continue reading
